DS21462B- page sensor 7 TC74 3. Digital Temperature Sensor and. It is available with a variety of ID numbers. Sensor ICs ( 32). Temperature data is converted from the on- board thermal sensing element and made available sensor as an 8- bit digital word. The system interface is a slave SMBus. tc74 All part types of the TC74 will operate properly over the wider power. Microchip Technology Inc.

This video demonstrates a very simple way to interface an I2C device using the PDQ Board. In this example, the I2C device is a TC74 temperature sensor. The TC74 has a resolution of 1 degree Celcius, with a range covering - 40 to 125 degrees.
